Uses

Notes

Fruit - raw or cooked[1]. An acid flavour, but it is rather nice raw especially when added to muesli or porridge[K]. Unfortunately, there is relatively little flesh and a lot of seeds[K]. The fruit can also be dried and used as raisins[2][3][4][5]. The ovoid fruit is about 12mm long[6].

Medicinal uses(Warning!)

The fruits are said to be diuretic and demulcent[8][1]. They are used in the treatment of dysentery[8].

A decoction of the bark is used as eye drops to treat inflammations of the eyes[1].

Berberine, universally present in rhizomes of Mahonia species, has marked antibacterial effects[9] and is used as a bitter tonic[10]. Since it is not appreciably absorbed by the body, it is used orally in the treatment of various enteric infections, especially bacterial dysentery[9]. It should not be used with Glycyrrhiza species (Liquorice) because this nullifies the effects of the berberine[9]. Berberine has also shown antitumour activity[9]. The root and root bark are best harvested in the autumn[10].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[11]. It usually germinates in the spring[K]. 'Green' seed (harvested when the embryo has fully developed but before the seed case has dried) should be sown as soon as it is harvested and germinates within 6 weeks[K]. Stored seed should be sown as soon as possible in late winter or spring. 3 weeks cold stratification will improve its germination, which should take place in 3 - 6 months at 10°c. Prick out the seedlings when they are large enough to handle and grow them on in a cold frame for at least their first winter. Plant them out in late spring or early summer.

Cuttings of half ripe wood 15cm long, July in individual pots in a frame[11]. Division of suckers in spring[11]. Whilst they can be placed direct into their permanent positions, better results are achieved if they are potted up and placed in a frame until established[12].

Leaf cuttings in the autumn.

Cultivation

An easily grown plant, it thrives in any good garden soil[12]. Grows well in heavy clay soils. Prefers a semi-shaded woodland position in a damp slightly acid to neutral humus rich soil[6]. Requires a position sheltered from cold or strong winds[13].

The plant is slightly tender in Britain[13] though it does well in Cornwall[14]. It under performs in areas where temperatures regularly fall below -10°c[6]. The young growth in spring can be damaged by late frosts[K]. Hybridizes freely with other members of this genus. The flowers have a delicate sweet fragrance[15]. At least one named variety has been developed for its ornamental value. 'Maharajah' appears to be hardier than the type species[16]. Closely allied to M. acanthifolia[12] (which is quoted as a synonym of this species in some books). The differences stated between the two species do not hold true in the wild but in cultivation M. acanthifolia has leaflets with a dull surface, flowers in the autumn and is hardier than many of the spring flowering introductions of M. nepaulensis.

Resistant to honey fungus[17].
